Spring的jdbcTemplate查询执行原生sql

  在spring与hibernate整合时进行数据库检索,执行原生sql:

  

public AppointmentEvaluateVo searchMyfeedbackDetail(String accountId, String fbId) {

        String sql = "select ae.id as fbId ,ae.app_id as appId, a.app_no as appNo,"
+ " si.service_item AS serItem,a.app_service_time as feedTime,ae.remark as"
+ " feedCon, cou.attitudeScore AS attitudeScore,cou.qualityScore AS qualityScore,"
+ "cou.prescriptionScore AS prescriptionScore from appointment_evaluate ae LEFT JOIN"
+ " appointment a ON ae.app_id=a.id LEFT JOIN organization_service_item osi "
+ "ON a.item_id=osi.id LEFT JOIN service_item si ON osi.service_item_id=si.id "
+ "LEFT JOIN ( SELECT _a.item_id, count(_a.id) AS orderNum, _ae.attitude as "
+ "attitudeScore, _ae.quality as qualityScore, _ae.prescription as prescriptionScore "
+ " FROM appointment _a RIGHT JOIN appointment_evaluate _ae ON `_a`.id = `_ae`.app_id "
+ " GROUP BY _a.item_id) cou ON osi.id = cou.item_id where 1=1 and ae.creator='" + accountId
+ "' and ae.id='" + fbId + "';"; List rows = jdbcTemplate.queryForList(sql);
AppointmentEvaluateVo av = new AppointmentEvaluateVo();
Iterator ite = rows.iterator();
while (ite.hasNext()) {
Map avMap = (Map) ite.next();
av.setFbId(avMap.get("fbId").toString());
av.setAppId(avMap.get("appId").toString());
av.setAppNo(avMap.get("appNo").toString());
av.setSerItem(avMap.get("serItem").toString());
av.setFeedTime(avMap.get("feedTime").toString());
av.setFeedCon(avMap.get("feedCon").toString());
av.setTotScore(avMap.get("prescriptionScore").toString());
av.setTquaScore(avMap.get("qulityScore").toString());
av.setSerScore(avMap.get("attitudeScore").toString());
}
return av;
}

  第二种:

  

public Student findStudentById(int id){
String sql = "select * from tb_student where id=?";
final Student student = new Student();
jdbcTemplate.query(sql,new Object[]{id},new RowCallbackHandler(){
public void processRow(ReultSet resultSet) throws SQLException{
student.setId(resultSet.getInt("id"));
student.setName(resultSet.getString("name"));
}
});
return student;
}
